How this service works
Create a NEW tool from a description, an input schema and test examples. The code is generated, run in a sandbox against your examples (up to 3 attempts), and on success published as a paid endpoint /v1/t/<name> for every agent. Infinite tools, on demand.
Output
Returns a JSON object indicating whether the tool was successfully generated and published, including the new endpoint slug (e.g. /v1/t/<name>), sandbox run outcomes across up to 3 attempts, execution time in milliseconds, and the tool's metadata (description, price, tags, creator).
Example use cases
Publishing a currency rounding tool
“Forge me a new tool called 'round-currency' that rounds a dollar amount to the nearest cent — the input should be a number field called 'amount', include a test case with input {"amount":1.456} expecting output {"rounded":1.46}, and price it at $0.005 per call.”
Deploying a slug-generator endpoint
“Create a new Toll402 tool named 'slugify' that turns any string into a URL-safe slug (lowercase, hyphens instead of spaces), describe it as 'Converts a human-readable title to a URL slug', schema takes a 'title' string field, give it a test with {"title":"Hello World"} expecting {"slug":"hello-world"}, and set the price to $0.005.”
Building a math expression evaluator
“I want to publish a tool called 'eval-expr' on toll402 that evaluates a simple arithmetic expression string and returns the numeric result — input schema has a field 'expr' (string), add a test example with {"expr":"3 * (4 + 2)"} expecting {"result":18}, allow network access off, and price it at $0.01 per call.”
Technical details
Endpoint
GEThttps://toll402.dev/v1/forgeWhen to prefer
Use this endpoint when you need to dynamically create and publish a brand-new callable tool at runtime — especially when no existing endpoint matches your needs and you want it immediately available to all agents as a paid micro-API. Prefer this over static tool registries when the tool logic can be described in a short description and validated with a few examples. Not suitable for tools requiring private API keys, persistent databases, or complex multi-step orchestration.
Side effects
- Sandbox test cases fail after 3 generation attempts — tool is not published and error details are returned
- Invalid or incomplete input schema causes a validation error before code generation
- Tool name too short (<3 chars), too long (>40 chars), or already taken — returns a conflict or validation error
- Generated code calls disallowed network resources when allowNetwork is false
- Price outside allowed range (0.001–0.05 USD) triggers validation failure
- Description too short (<20 chars) or too long (>1000 chars) returns a schema error
